Quick and Easy Pickled Red Onions

Quick and Easy Pickled Red Onions are a simple easy refrigerator pickle project to add to your repertoire ~ they’re not only beautiful, they’re a workhorse when it comes to jazzing up lots of different kinds of foods!

Pickled onions make just about anything better!

You can’t make a great fish taco without pickled onions, but they are also great on sandwiches, burgers and hotdogs, salads, cheese boards…pretty much anywhere you’d use sliced onions. Pickling takes a bit of the raw bite off of onions and replaces it with a nice sweet-sour tang. And like most pickles they’re almost calorie free, so they are a great way to add interest and flavor to food if you’re watching your weight.

Pickled red onions change from purple to vivid pink

It’s a fun chemistry experiment to watch the purple onions turn bright pink the minute they hit the acidic vinegar. I love the vibrant color of these pickled red onions, they really brighten up food in more ways than one!

The method for these pickles is very simple and lends itself well to adaptation and experimentation.

I used a few extra spices like multicolored peppercorns, yellow mustard seeds, and cumin seeds, but feel free to substitute in others. And just one sliced jalapeno pepper makes the whole jar pretty hot. But you can do this without any spices at all if you want to. The classic combination of vinegar, salt and sugar also makes a wonderful simple pickle.

I love making quick pickles–you can pickle all kinds of vegetables and it’s nice to have a little collection in the fridge so you have just the right pickle for all your recipes! Here are a few more of my favorites that are easy, fast, and sure to brighten up any dish.
